"Main_Data.Rdata" is the final dataset for main analysis.

“well_info.csv” contains detailed information for every individual unconventional well.

"Monitor_AOD.Rdata" contains AOD measurements for areas around ground monitors.

Data in "PM2.5" subfolder are monitor PM2.5 data from EPA database.

Data in "Mortality" subfolder are mortality data from CDC WONDER database.

Data in "socio_econ_data" folder are supplement socio-economic data and block group shape file are are used in the analysis.

“Fracking_Analysis_Code.R” is the R code that uses “Main_Data.Rdata” and “well_info.csv” to produce results.

"PSM.R" is the R code that uses files in "socio_econ_data" subfolder to conduct propensity score matching and produce column (3) in Table 4: results using matched samples

"Mortality_Impact_Analysis.R" is the R code that uses "Monitor_AOD.Rdata" and files in "PM2.5" subfolder to link AOD to PM2.5 ground monitor data, and then uses files in "socio_econ_data" and "Mortality" subfolder to estimate the mortality impact (Section 7 of the main paper).
